Single-stage reconstruction for buccal mucosa tumor resection including the labial commissure using a facial artery musculomucosal flap and a vermilion advancement flap

Abstract

Resection of buccal mucosa tumors may occasionally involve the labial angle and peripheral skin. Reconstruction is required when the resection involves more than one-third of the lip. We describe a single-stage reconstruction using a facial artery musculomucosal (FAMM) flap and a vermilion advancement flap after buccal mucosa resection including the labial angle. A 62-year-old woman with carcinoma in situ of the buccal mucosa underwent tumor resection. The resection included the right labial angle and peripheral skin. The resection did not lead to a massive lip defect, but a wide defect resulted on the mucosal side. The defect on the mucosal side was reconstructed using a FAMM flap, while the vermilion defect was covered using a vermilion advancement flap. Reconstruction performed using the FAMM flap and vermilion advancement flap produced aesthetically and functionally satisfactory outcomes.
